does anyone know where i can get the wireing harness to stack and edge ez with a race pro comp box or blue chip diesel fms

 

just plug one into the other. . .but you need to make sure you have them connected up properly. . .I would say you need to let the edge see exactly what the engine is doing, so connect that first. then use the other box to fine tune

 

they both hav to plug into the same port on the cummins engine need a cable that would allow that tatext

 

it works like this. . .I know both use the MAP sensor. . .you unplug the stock harness, plug in the edge connector, then where you would plug in the stock harness into the edge, you would plug in the other module. then the stock connector into the return, and so on.

it will plug into each other, you just have to be carefull in what order you plug them in.

 

i would just get a chip and then a programmer...alot more easy!

 

true. . .but plug in boxes are less expensive and are shift on the fly

 

both of the boxes have a plug for the diagnostic port and you need a wireing harness to replicate that port in series to finish the install the rest is basic and i already have the two chips

 

edge you shouldnt have to plug into the disgnostic at all right? but thats cool hope it works for you

 

OOOOHHHHHHH. . .I gotcha now. . .this will be an interesting stack

 

that is the data port on the cummins engine not the diagnostic port but i am still looking for a port duplicator thanks
